i have to make biology investigatory project of class 12 cbse on topic ecosystem.i dont know how to make it .please give me a sample project and help me to do this
what is the limitation of detritus food chain?
How would you explain the paradox that the pyramid of biomass in sea is inverted because biomass of fishes exceeds that of phytoplankton?
pyramid of energy is always uprightupwards.why?
What does this line means,"In an aquatic system, GFC is the major conduit for energy flow" ?
If we were to count the no. of insects feeding on a big tree,we would get an inverted pyramid.Why??
measurement of biomass in terms od dry weight is more accurate. why?

plz help me on this . give the names of @least 13 common medicinal plants ?
who perfomed the blender experiment in regard to certain nature of dna? what was the objective of this experiment ? pls explain the procedure in details
Difference between standing crop and standing state
State the difference between the first trophic level of detritus food chain and grazing food chain.
The first trophic level of detritus food chain is often the dead and decaying organic matter whereas the grazing food chain starts with the living green plants.
The first trophic level organisms of detritus food chain are saprophytes whereas the starters of grazing food chain are producers.
Is that second point actually right? How can the organic matter and saprophytes be the same?Aren't saprophytes the consumers of detritus?Correct me if i'm wrong.
what is meant by term ecological succession?? provide details regarding ecological succession on land and water.
what is meant by FADH2 and NADH2 in bioenegetics???what r its functions?
pls explain this....
ecosystems are not exempt from the second law of thermodynamics.they need a constant supply of energy to synthesise the molecules they require,to counteract the universal tendency towars increasing disorderliness.
Define ecological pyramids and describe with examples, pyramids of number and biomass.
Differences between Carbon and Phosphorous cycle ?
why measurement of biomass in terms of dry weight is more accurate?
1. In an ecosystem dominated by trees, the pyramid (of numbers) is _________ type. How is it inverted ? Can't it be spindle shaped too?
2.Which one of the following has the largest population in a food chain? shouldnt it be producers as decomposers are not included in the food chain?.
what is the difference between regulators and conformers
why is the pyramid of biomass of phytoplankton inverted ?
when is the pyramid of biomass spindle shaped?
DRAW THE PYRAMID OF BIOMASS IN A SEA AND IN A FOREST. EXPLAIN GIVING REASONS WHY THE TWO PYRAMID IS DIFFERENT?
suggest some investigatory projects of biology

plz help me...
the differences between grazing food chain and detritus food chain ?
1) Vertical distribution of different species occupying different levels is called ___________.
2) Of the incident solar radiation (on earth) less than 50% of it is __________________.
meaning of detritus?
what are plant hormones? give the uses of the plant hormones like auxins,gibberlins,cytokinins and artificial hormones like ABA,ethylene??
why does human body maintain constant temperature both in summerss and winters ?
Why is the pyramid of biomass inverted in a pond ecosystem?

A man who is eating curd/yoghurt can be placed in which trophic level and why?
Why Saprophytes are not included in pyramids?
What is the difference between decomposers and detritivores?
1). first trophic level
2). second trophic level
3). third trophic level
4). fourth trophic level
its answer according to me should be fourth trophic level as first one are plants, second is cow, third should be bacteria which convert milk into curd fourth one should be the man eating the curd, but given answer is third trophic level. but how?
Ans net osmosis occur from B to A
Chamber B has higher solute potential
